NTAs are aggregations of census tracts that approximate neighborhoods, with each having a population sizable enough to ensure confidence in the results. For more information on 2020 NTAs, and changes from 2010, see 2020 Census Reconfiguration of Statistical Geographies.
Dependency ratios have developed into a commonly used index for measuring the social and economic impact of age structures in societies. For our map we adopted the old-age dependency definition used in the American Community Survey, which characterizes people between the ages of 18 and 64 as the “working age” population and the population 65 years and older as “retirement age.” They adopted 18 years old as the lower bound for the “working age” population as it is typically the age when the average person in the United States begins to lead a more independent life.
